About the role
As a Sr. Infrastructure Engineer I , you will play a critical role in the Mainframe Pod of Symetra’s Infrastructure & Operations team. This position requires a solid focus on Mainframe Operations while serving as a key conduit between application teams and our managed service provider. The successful candidate will ensure reliable day-to-day operations, lead coordination of incident and request handling, and contribute to roadmap and modernization initiatives.
This role demands both hands-on technical expertise in mainframe environments and collaborative leadership skills to align partners and keep systems running securely and efficiently.
What you will do
• Act as a main contact for mainframe operations, overseeing daily health, stability, and performance of mainframe systems and tools.
• Serve as the bridge between application teams and the managed service provider, ensuring clear communication, timely resolution of issues, and effective coordination of changes and upgrades.
• Manage Service Requests and Incidents from application teams, providing hands-on troubleshooting and advancing to service providers when necessary.
• Manage and monitor ESP Scheduler activities, including scheduling, execution, and troubleshooting of batch and on-demand workloads.
• Partner with application teams to optimize and maintain ESP job schedules, calendars, and dependencies.
• Coordinate and oversee mainframe application upgrades and changes, partnering with app teams and the service provider to minimize risk and downtime.
• Provide primary support for key applications such as Endevor, Terminal Emulator, Control-D and related tools.
• Support audit and compliance activities, ensuring proper documentation and alignment to regulatory standards.
• Deliver architectural input and technical evaluations of applications, guiding app teams on mainframe-related best practices.
• Support real-time integrations and web services that connect distributed platforms to the mainframe.
• Participate in and influence mainframe modernization efforts, helping transition legacy workloads toward more agile, integrated, and automated approaches.
Why Work at Symetra
Here’s what some of our employees have to say about why they work at Symetra:
"Symetra will spoil you. There aren't many companies that will put as much effort into you being a success as Symetra. The culture will challenge you but simultaneously put you at ease. Failure is seen as integral to the learning process so there is less reason to be fearful of it." - Kerry S., Sr. Systems Analyst
“If you want to invest in yourself and build a career, this is a great place to work. If you don't want to put in the effort to learn the industry and become a student of the business (it takes real effort!), there are easier places to work.” - Cris H., VP Internal Sales
